In the 2022 good grapefruit tree and orchard contest in Yen Binh, that of Le Van Minh in Kha Linh hamlet won the first prize.

Currently, Minh's family is growing grapefruit on over two hectares with about 800 trees which can be harvested, of which Kha Linh grapefruit is planted on nearly one hectare. To join the contest, Minh's family selected more than 10 Kha Linh grapefruit trees aged over 60.

At present, Dai Minh commune has more than 30 ancient grapefruit trees which are over 100 years old. This precious variety is also planted in surrounding areas, but only develops enough special delicious flavour when being grown on Dai Minh's land.

The commune has many models of grapefruit plantations, ancient grapefruit orchards, and model orchards with large scales; and has actively applied scientific and technical advances to the development of grapefruit trees following VietGAP, and organic standards. 

Dai Minh grapefruit is harvested from the 10th lunar month to the first of the next year. Traders must go to the orchard to book the purchase right from the time the trees are fruiting. Currently, the commune has 425 hectares, with the 2022 output reaching nearly 4,950 tonnes worth over 50 billion VND. This kind of fruit was recognised as a 3-star OCOP (one commune one product) product. The fruit has been present in supermarkets and restaurants in Hanoi as well as many localities throughout the country.

Ten households in the commune competed in this year’s good grapefruit tree and orchard contest. These are Kha Linh grapefruit orchards with an age of over 30 years, and an area of at least 0.3 ha. These households and cooperatives actively select grapefruits with high quality and beautiful shells to participate in the Dai Minh Grapefruit and Thac Ba Lake Exploration Festival, contributing to promoting the fruit to customers inside and outside the province.
